Most of us here are not particularly big fans of the concept of patents. Most of us are aware of the significance of patents, we just believe the system has gone out of control and needs a serious kick in the butt. Well, it turns out not even the richest people on this earth are immune to the call of the patent troll. Microsoft co-founder Paul Allen has filed a massive patent lawsuit, using broad and vague patents to sue just about any big name in the business - from Apple to Google.

I imagine that the reason it's hard to show that patents work is because they don't work. Patents are supposed to promote progress, and progress is measurable. There is no historical data suggesting that Patents have increased progress when introduced to countries and industries, however there is some data suggesting that it might have reduced progress.
